No. The absence of evidence is not evidence of presence. There are solid scientific reasons to suspect we might be alone in our local volume of the universe. IMHO, these reasons now outweigh the arguments in favour of alien intelligence. The default scientific position is skepticism. It is an abundance of proof that is required to overcome it, not "belief." Belief in the absence of evidence is not a scientific position.

I do find it to be a curious coincidence that "belief" in aliens visiting earth shares so many characteristics with devout religious belief. Just replace OP's references to aliens with references to the deity of choice and you'll get the idea.
